I just feel so sad and I know its because of my depression but what the hell am I depressed about?? I don't even know. maybe I just wish today could've been different. I wish I couldve actually went to my man and my sisters graduation today. but I couldn't go because I'm pregnant and the day should be focused on the graduates instead of everyone finding out about my pregnancy. its as if my son is resented and I don't like that feeling at all. I get its graduation. I've spent the whole school year staying away from their high school. I've missed sporting events and dances with my man. you would think by graduation if people saw that I was pregnant, yes it would be something they'd talk about, but it wouldn't matter because I no longer attend there and neither does my man or sister. *sigh* I just don't know
